Description

本発明は、例えば車両に配置され、バッテリ充電を行うための充電インレット装置に関する。   The present invention relates to a charging inlet device that is disposed, for example, in a vehicle and performs battery charging.

電気自動車（ＥＶ）やハイブリッド電気自動車（ＨＥＶ）等の車両に搭載されるバッテリを充電するために、車両には充電インレット装置が設けられる（特許文献１、２参照）。充電インレット装置の一従来例として図７に示すものがある。   In order to charge a battery mounted on a vehicle such as an electric vehicle (EV) or a hybrid electric vehicle (HEV), the vehicle is provided with a charging inlet device (see Patent Documents 1 and 2). A conventional example of the charging inlet device is shown in FIG.

図７において、充電インレット装置５０は、内部に端子（図示せず）が収容されたコネクタハウジング５１と、このコネクタハウジング５１の外周を被うように配置された外装ケース５２と、この外装ケース５２の一端部に回転自在に支持されたキャップ５３とを備えている。   In FIG. 7, a charging inlet device 50 includes a connector housing 51 in which terminals (not shown) are accommodated, an outer case 52 disposed so as to cover the outer periphery of the connector housing 51, and the outer case 52. And a cap 53 that is rotatably supported at one end.

コネクタハウジング５１は、円筒状で、この円筒状の前面を塞ぐ前面壁５４を有する。前面壁５４には、端子挿入孔５５が設けられている。この端子挿入孔５５より相手端子（図示せず）が挿入される。挿入された相手端子が内部の端子（図示せず）に電気的に接続される。   The connector housing 51 is cylindrical, and has a front wall 54 that closes the cylindrical front surface. A terminal insertion hole 55 is provided in the front wall 54. A mating terminal (not shown) is inserted through the terminal insertion hole 55. The inserted counterpart terminal is electrically connected to an internal terminal (not shown).

外装ケース５２には、キャップロック部５２ａが設けられている。   The outer case 52 is provided with a cap lock portion 52a.

キャップ５３は、前面壁５４に密着して端子挿入孔５５を塞ぐ閉位置と、前面壁５４より離間して端子挿入孔５５を開放する開位置（図７の位置）との間で回転自在に設けられている。キャップ５３は、ねじりコイルバネ６０によって開位置側に付勢されている。キャップ５３には、キャップ５３が開位置より閉位置まで回転されると、キャップ５３の係止部５３ａがキャップロック部５２ａにロックされる。これにより、キャップ５３は、閉位置に位置保持される。   The cap 53 is rotatable between a closed position where the cap 53 is in close contact with the front wall 54 and closes the terminal insertion hole 55, and an open position (position in FIG. 7) where the cap 53 is spaced apart from the front wall 54 and opens the terminal insertion hole 55. Is provided. The cap 53 is biased toward the open position by the torsion coil spring 60. When the cap 53 is rotated from the open position to the closed position, the locking portion 53a of the cap 53 is locked to the cap lock portion 52a. As a result, the cap 53 is held in the closed position.

キャップ５３の内面には、パッキン５６が設けられている。パッキン５６は、外装ケース５２の前端部と同等若しくは若干大きな外径寸法に設定されている。キャップ５３が閉位置に位置する場合には、パッキン５６が前面壁５４に直接密着する。これにより、端子挿入孔５５に水、塵埃等が侵入するのを確実に防止している。   A packing 56 is provided on the inner surface of the cap 53. The packing 56 is set to have an outer diameter that is equal to or slightly larger than that of the front end portion of the outer case 52. When the cap 53 is in the closed position, the packing 56 is in direct contact with the front wall 54. This reliably prevents water, dust and the like from entering the terminal insertion hole 55.

パッキン５６は、車両の軽量化の観点から軽い部材で、且つ、隙間防止やガタ付き防止の観点から弾力に優れた部材が好ましい。そのため、従来では、ゴム系（例えば発泡ゴム）のパッキンが使用されている。   The packing 56 is a light member from the viewpoint of reducing the weight of the vehicle, and a member excellent in elasticity from the viewpoint of preventing gaps and rattling. Therefore, conventionally, rubber-based (for example, foamed rubber) packing is used.

しかしながら、ゴム系材料のパッキン５６は、キャップ５３を閉位置に長時間の間位置させていると、前面壁５４への貼り付きが発生し、キャップロック部５２ａを解除してもねじりコイルバネ６０のバネ力のみでは開位置に回転しない事態が発生する。その際は、ユーザが手で直接キャップ５３を開く必要があり、キャップ開閉操作が面倒である。   However, if the cap 53 is kept in the closed position for a long time, the rubber-based material packing 56 sticks to the front wall 54, and even if the cap lock portion 52a is released, the torsion coil spring 60 is released. A situation occurs in which the spring does not rotate to the open position only by the spring force. In that case, it is necessary for the user to open the cap 53 directly by hand, and the cap opening / closing operation is troublesome.

そこで、本発明は、前記した課題を解決すべくなされたものであり、キャップの貼り付きを極力防止できる充電インレット装置を提供することを目的とする。   Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a charging inlet device that can prevent sticking of a cap as much as possible.

本発明は、前面壁に端子挿入孔が設けられ、前記端子挿入孔より相手端子が挿入されるコネクタハウジングと、前記前面壁に密着して前記端子挿入孔を塞ぐ閉位置と、前記前面壁より離間して前記端子挿入孔を開放する開位置との間で移動自在に設けられたキャップと、前記キャップの内面に配置されたパッキンとを備えた充電インレット装置であって、前記前面壁と前記パッキンの少なくともいずれか一方には、前記端子挿入孔以外の領域で互いに密着しない非密着領域が設けられており、前記非密着領域は、前記前面壁に凹部を設けることによって構成されており、前記凹部の内側面は、前記コネクタハウジングの前面壁が垂直方向に対して上向きになる取付角度で車両設置され、前記凹部の内側面の傾斜角度が前記取付角度より大きく設定されている車両設置状態で、前記凹部の内側面の最下方位置の形態が、前記凹部の奥から入口に行くに従って下方に傾斜している傾斜面となることを特徴とする充電インレット装置である。 The present invention includes a connector housing in which a terminal insertion hole is provided in a front wall, and a mating terminal is inserted from the terminal insertion hole, a closed position in close contact with the front wall and closing the terminal insertion hole, and the front wall A charging inlet device comprising a cap provided to be movable between an open position that is spaced apart to open the terminal insertion hole, and a packing disposed on an inner surface of the cap, wherein the front wall and the At least one of the packings is provided with a non-contact region that does not adhere to each other in a region other than the terminal insertion hole, and the non-contact region is configured by providing a recess in the front wall, inner surface of the recess includes a front wall of the connector housing is a vehicle placed in the mounting angle facing up with respect to the vertical direction, the inclination angle of the inner surface of the recess is larger than the mounting angle In a vehicle installation state that is constant, the form of the lowest position of the inner surface of the recess, at charging inlet device, characterized in that an inclined surface that is inclined downward as the inner toward the entrance of the recess is there.

前記非密着領域は、前記パッキンにも切欠部を設けることによって構成しても良い。 Before Stories non-contacted region may be constituted by in the packing providing a notch.

本発明によれば、パッキンと前面壁との密着面積が減小し、これによりパッキンの貼り付き力が低下する。以上より、キャップの貼り付きを極力防止できる。   According to the present invention, the contact area between the packing and the front wall is reduced, thereby reducing the sticking force of the packing. As mentioned above, sticking of a cap can be prevented as much as possible.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１〜図５は本発明の一実施形態を示す。図１〜図３に示すように、充電インレット装置１は、内部に端子９が収容されたコネクタハウジング２と、このコネクタハウジング２の外側面を被うように配置された外装ケース１０と、この外装ケース１０の一端部に回転自在に支持されたキャップ２０とを備えている。   1 to 5 show an embodiment of the present invention. As shown in FIGS. 1 to 3, the charging inlet device 1 includes a connector housing 2 in which terminals 9 are accommodated, an outer case 10 disposed so as to cover the outer surface of the connector housing 2, A cap 20 is rotatably supported at one end of the outer case 10.

コネクタハウジング２は、円筒状で、この円筒状の前面を塞ぐ前面壁３を有する。前面壁３には、複数の端子挿入孔４が設けられている。この各端子挿入孔４より相手端子（図示せず）が挿入される。挿入された相手端子が内部の端子９に電気的に接続される。前面壁３の外面には、複数の凹部５が設けられている。この凹部５については、下記に詳述する。   The connector housing 2 is cylindrical and has a front wall 3 that closes the cylindrical front surface. The front wall 3 is provided with a plurality of terminal insertion holes 4. A mating terminal (not shown) is inserted through each terminal insertion hole 4. The inserted counterpart terminal is electrically connected to the internal terminal 9. A plurality of recesses 5 are provided on the outer surface of the front wall 3. The recess 5 will be described in detail below.

外装ケース１０は、ほぼ円筒状の嵌合ケース部１１と、この嵌合ケース部１１の後端側に一体に設けられたブラケット部１２とを有する。ブラケット部１２を介して充電インレット装置１が車両側に固定される。嵌合ケース部１１とコネクタハウジング２の外周との間には、相手側（例えば充電スタンド側）のコネクタハウジング（図示せず）の嵌合スペースＳが設けられている。   The outer case 10 includes a substantially cylindrical fitting case portion 11 and a bracket portion 12 provided integrally on the rear end side of the fitting case portion 11. The charging inlet device 1 is fixed to the vehicle side via the bracket portion 12. Between the fitting case portion 11 and the outer periphery of the connector housing 2, a fitting space S of a connector housing (not shown) on the other side (for example, the charging stand side) is provided.

嵌合ケース部１１の一端側には、一対のキャップ支持部１３が設けられている。この一対のキャップ支持部１３には、回転支持ピン１４が固定されている。この回転支持ピン１４には、ねじりコイルバネ３０が支持されている。ねじりコイルバネ３０は、その一端側が嵌合ケース部１１に、他端側がキャップ２０にそれぞれ掛止されている。   A pair of cap support portions 13 is provided on one end side of the fitting case portion 11. A rotation support pin 14 is fixed to the pair of cap support portions 13. A torsion coil spring 30 is supported on the rotation support pin 14. One end of the torsion coil spring 30 is hooked on the fitting case portion 11 and the other end is hooked on the cap 20.

嵌合ケース部１１の他端側には、キャップロック部１５が設けられている。キャップロック部１５は、嵌合ケース部１１にロック位置とロック解除位置との間で揺動自在に支持されている。キャップロック部１５は、ねじりコイルバネ３５によってロック位置側に付勢されている。   A cap lock portion 15 is provided on the other end side of the fitting case portion 11. The cap lock portion 15 is supported by the fitting case portion 11 so as to be swingable between a lock position and a lock release position. The cap lock portion 15 is biased toward the lock position by a torsion coil spring 35.

キャップ２０は、略円板状である。キャップ２０は、その一端側に支持部２１を有し、他端側に係止部２２を有する。支持部２１は、回転支持ピン１４に回転自在に支持されている。これにより、キャップ２０は、前面壁３に密着して端子挿入孔４及び嵌合スペースＳを塞ぐ閉位置（図２の位置）と、前面壁３より離間して端子挿入孔４及び嵌合スペースＳを開放する開位置（図１の位置）との間で回転自在に支持されている。キャップ２０は、ねじりコイルバネ３０によって開位置側に付勢されている。キャップ２０には、キャップ２０が開位置より閉位置まで回転されると、キャップ２０の係止部２２がキャップロック部１５にロックされる。これにより、キャップ２０は、閉位置に位置保持される。   The cap 20 has a substantially disk shape. The cap 20 has a support portion 21 on one end side and a locking portion 22 on the other end side. The support portion 21 is rotatably supported by the rotation support pin 14. Thereby, the cap 20 is in close contact with the front wall 3 to close the terminal insertion hole 4 and the fitting space S (position shown in FIG. 2), and the cap 20 is separated from the front wall 3 and the terminal insertion hole 4 and the fitting space. It is supported so as to be rotatable between an open position where S is opened (position in FIG. 1). The cap 20 is biased toward the open position by the torsion coil spring 30. When the cap 20 is rotated from the open position to the closed position, the locking portion 22 of the cap 20 is locked to the cap lock portion 15. As a result, the cap 20 is held in the closed position.

キャップ２０の内面には、ほぼ円板状のパッキン２５が設けられている。パッキン２５は、外装ケース１０の前端部と同等若しくは若干大きな外径寸法に設定されている。キャップ２０の閉位置では、パッキン２５がコネクタハウジング２の前面壁３及び外装ケース１０の前端部に直接密着する。   A substantially disc-shaped packing 25 is provided on the inner surface of the cap 20. The packing 25 is set to have an outer diameter that is the same as or slightly larger than the front end of the outer case 10. In the closed position of the cap 20, the packing 25 is in direct contact with the front wall 3 of the connector housing 2 and the front end portion of the outer case 10.

パッキン２５は、車両の軽量化の観点から軽い部材で、且つ、隙間防止（封止性）やガタ付き防止（異音防止）の観点から弾力に優れた部材、例えば発泡ゴムより形成されている。   The packing 25 is a light member from the viewpoint of reducing the weight of the vehicle, and is formed of a member having excellent elasticity from the viewpoint of preventing gaps (sealing properties) and preventing looseness (preventing abnormal noise), for example, foam rubber. .

一方、コネクタハウジング２の前面壁３には、上記したように複数の凹部５が設けられている。各凹部５は、端子挿入孔４に連続しないように設けられている。凹部５は、下記するようにキャップ２０の閉位置では前面壁に密着しない領域となる。つまり、この実施形態では、凹部５によって非密着領域が構成されている。   On the other hand, the front wall 3 of the connector housing 2 is provided with a plurality of recesses 5 as described above. Each recess 5 is provided so as not to be continuous with the terminal insertion hole 4. As will be described below, the recess 5 is a region that does not adhere to the front wall when the cap 20 is closed. That is, in this embodiment, the non-contact region is constituted by the recess 5.

各凹部５は、図４及び図５に詳しく示すように、コネクタハウジング２の前面壁３が垂直方向に対して上向きになる取付角度Ａで車両設置される場合にあって、凹部５の内側面５ａの傾斜角度Ｂが取付角度Ａより大きく設定されている。これにより、凹部５の内側面５ａは、車両設置状態にあって、その最下方位置が水平方向より下方に傾斜する傾斜面となるように設けられている。 As shown in detail in FIGS. 4 and 5, each recess 5 is provided when the vehicle is installed at a mounting angle A in which the front wall 3 of the connector housing 2 faces upward with respect to the vertical direction. The inclination angle B of 5a is set larger than the attachment angle A. Thus, the inner surface 5a of the recess 5, in the vehicle installation state, its lowest position are provided so as to be inclined surface inclined downwardly from the horizontal direction.

上記構成において、図４に示すように、キャップ２０が閉位置に位置する場合には、パッキン２５がコネクタハウジング２の前面壁３に密着する。これにより、前面壁３の端子挿入孔４が塞がれ、端子挿入孔４より水、塵埃等がコネクタハウジング２内に侵入するのを防止する。キャップロック部１５をロック解除位置に操作すると、ねじりコイルバネ３０のバネ力によってキャップ２０が閉位置より開位置に回転する。これにより、コネクタハウジング２の端子挿入孔４が開放される。相手側のコネクタハウジング（図示せず）が嵌合可能となる。   In the above configuration, as shown in FIG. 4, when the cap 20 is located at the closed position, the packing 25 is in close contact with the front wall 3 of the connector housing 2. Thereby, the terminal insertion hole 4 of the front wall 3 is closed, and water, dust, etc. are prevented from entering the connector housing 2 from the terminal insertion hole 4. When the cap lock portion 15 is operated to the unlocked position, the cap 20 is rotated from the closed position to the open position by the spring force of the torsion coil spring 30. Thereby, the terminal insertion hole 4 of the connector housing 2 is opened. A mating connector housing (not shown) can be fitted.

キャップ２０の閉位置にあって、パッキン２５は、端子挿入孔４の位置と共に凹部５の位置でも前面壁３に密着しないため、前面壁３との密着面積が従来例に較べて小さく、これによりパッキン２５の貼り付き力が低い。そのため、キャップ２０を閉位置に長時間の間位置させていても、前面壁３への貼り付き力が小さく、キャップロック部１５を解除するとねじりコイルバネ３０のバネ力のみによって開位置に確実に回転する。以上より、キャップ２０の貼り付きを極力防止できる。   In the closed position of the cap 20, the packing 25 does not adhere to the front wall 3 even at the position of the recess 5 as well as the position of the terminal insertion hole 4. Therefore, the contact area with the front wall 3 is smaller than that of the conventional example. The sticking force of the packing 25 is low. Therefore, even if the cap 20 is kept in the closed position for a long time, the sticking force to the front wall 3 is small, and when the cap lock portion 15 is released, the cap 20 is reliably rotated to the open position only by the spring force of the torsion coil spring 30. To do. From the above, sticking of the cap 20 can be prevented as much as possible.

凹部５の内側面５ａは、充電インレット装置１の車両設置状態にあって、その最下方位置が水平方向より下方に傾斜する傾斜面となるように設けられている。従って、凹部５に水等が入り込んでも自重によって排出するため、凹部５に水等が溜まることがない。 The inner side surface 5a of the recess 5 is provided so that the lowermost position of the inner surface 5a of the charging inlet device 1 is an inclined surface inclined downward from the horizontal direction. Therefore, even if water or the like enters the recess 5, it is discharged by its own weight, so that water or the like does not accumulate in the recess 5.

図６には変形例に係る充電インレット装置１Ａが示されている。変形例の充電インレット装置１Ａは、前記実施形態と比較するに、コネクタハウジング２の前面壁３には凹部５が設けられておらず、その代わりにパッキン２５に切欠部２５ａが複数設けられている。各切欠部２５ａは、前面壁３の端子挿入孔４の位置に対応しない位置に設けられている。切欠部２５ａは、キャップ２０の閉位置では前面壁３に密着しない領域となる。つまり、この変形例では、切欠部２５ａによって非密着領域が構成されている。   FIG. 6 shows a charging inlet device 1A according to a modification. Compared with the above-described embodiment, the charging inlet device 1A according to the modified example is not provided with the recess 5 in the front wall 3 of the connector housing 2, but is provided with a plurality of cutouts 25a in the packing 25 instead. . Each notch 25 a is provided at a position not corresponding to the position of the terminal insertion hole 4 on the front wall 3. The notch 25a is a region that does not adhere to the front wall 3 when the cap 20 is closed. That is, in this modification, the non-contact region is configured by the notch 25a.

他の構成は、前記実施形態と同様であるため、重複説明を省略する。図６には、前記実施形態の同一構成箇所には、同一符号を付して明確化を図る。   Since other configurations are the same as those of the above-described embodiment, a duplicate description is omitted. In FIG. 6, the same reference numerals are given to the same components in the embodiment for clarification.

この変形例では、パッキン２５は、キャップ２０の閉位置では端子挿入孔４の位置と共に切欠部２５ａの位置でも前面壁３に密着しないため、前面壁３との密着面積が従来例に較べて小さく、これによりパッキン２５の貼り付き力が低い。そのため、前記実施形態と同様に、キャップ２０の貼り付きを極力防止できる。尚、切欠部２５ａは、この明細書では、有底の溝（凹部）を含む。   In this modification, the packing 25 is not in close contact with the front wall 3 at the position of the notch 25a as well as the position of the terminal insertion hole 4 in the closed position of the cap 20, so the contact area with the front wall 3 is smaller than in the conventional example. Thereby, the sticking force of the packing 25 is low. Therefore, similarly to the embodiment, sticking of the cap 20 can be prevented as much as possible. In this specification, the cutout portion 25a includes a bottomed groove (concave portion).

また、コネクタハウジング２の前面壁３に凹部５を設け、且つ、パッキン２５に切欠部２５ａを設けても良い。その際には、凹部５の位置と切欠部２５ａの位置を異ならせても、又、同位置位置でも、更に、一部重複する位置でも良い。   Further, the recess 5 may be provided in the front wall 3 of the connector housing 2, and the notch 25 a may be provided in the packing 25. In that case, the position of the recess 5 and the position of the notch 25a may be different, or the position may be the same position, or may be a partially overlapping position.
